Pull ARM SoC defconfig updates from Arnd Bergmann:
"As usual, a bunch of commits, mostly adding drivers and other options
to defconfigs.
The realview_smp_defconfig and realview_defconfig got merged into one,
so we are now down to 110 files.
For stm32, we have now added a Kconfig fragment, the first such file
on arch/arm. The purpose here is to have a shared defconfig file that
works for all boards, while the DRAM offset has to be hardwired on
NOMMU machines at compile time.
The Exynos defconfig changes depend on changes in the RTC tree, so
this is pulled in here, but has already been merged into 4.6 now"

This reverts commit a59f8c5b048dc938fb958c91c282c865cd845705.
There are several bugs in this new code, for example:
1) Uses sleeping locks in get_stats64, which is not allowed,
as the operation can be invoked in an atomic context.
2) Uses PM fields without CONFIG_PM or similar guards.
3) Does not synchronize HW stats when the device runtime
suspends.
Therefore this is being reverted until a correct version
is implemented.

Commit 2213e9a66bb8 ("kallsyms: add support for relative offsets in
kallsyms address table") changed the default kallsyms symbol table
format to use relative references rather than absolute addresses.
This reduces the size of the kallsyms symbol table by 50% on 64-bit
architectures, and further reduces the size of the relocation tables
used by relocatable kernels. Since the memory footprint of the static
kernel image is always much smaller than 4 GB, these relative references
are assumed to be representable in 32 bits, even when the native word
size is 64 bits.
On 64-bit architectures, this obviously only works if the distance
between each relative reference and the chosen anchor point is
representable in 32 bits, and so the table generation code in
scripts/kallsyms.c scans the table for the lowest value that is covered
by the kernel text, and selects it as the anchor point.
However, when using the GOLD linker rather than the default BFD linker
to build the x86_64 kernel, the symbol phys_offset_64, which is the
result of arithmetic defined in the linker script, is emitted as a 'T'
rather than an 'A' type symbol, resulting in scripts/kallsyms.c to
mistake it for a suitable anchor point, even though it is far away from
the actual kernel image in the virtual address space. This results in
out-of-range warnings from scripts/kallsyms.c and a broken build.
So let's align with the BFD linker, and emit the phys_offset_[32|64]
symbols as absolute symbols explicitly. Note that the out of range
issue does not exist on 32-bit x86, but this patch changes both symbols
for symmetry.

'struct timeval' uses 32-bit representation for seconds which will
overflow in year 2038 and beyond. mISDN/clock.c needs to compute and
store elapsed time in intervals of 125 microseconds. This patch replaces
the usage of 'struct timeval' with 64-bit ktime_t which is y2038 safe.
The patch also replaces do_gettimeofday() (wall-clock time) with
ktime_get() (monotonic time) since we only care about elapsed time here.

Jesse Gross says:
====================
Tunneling fixes
This series fixes a problem that was reported where encapsulated packets
do not have their encapsulation offload markers stripped off when being
decapsulated. This causes a significant performance drop if the packets
are later retransmitted.
Fixing this revealed two other bugs which are also addressed as prerequisites:
* GRO can aggregate packets for multiple layers of encapsulation which the
stack cannot properly handle.
* IPIP packets which are combined by GRO are not marked properly with their
GSO type.
Note that this is based off the net-next tree as the current target for
bug fixes.
v2: No code changes, just additional information in commit messages and
a new cover letter.

If a packet is either locally encapsulated or processed through GRO
it is marked with the offloads that it requires. However, when it is
decapsulated these tunnel offload indications are not removed. This
means that if we receive an encapsulated TCP packet, aggregate it with
GRO, decapsulate, and retransmit the resulting frame on a NIC that does
not support encapsulation, we won't be able to take advantage of hardware
offloads even though it is just a simple TCP packet at this point.
This fixes the problem by stripping off encapsulation offload indications
when packets are decapsulated.
The performance impacts of this bug are significant. In a test where a
Geneve encapsulated TCP stream is sent to a hypervisor, GRO'ed, decapsulated,
and bridged to a VM performance is improved by 60% (5Gbps->8Gbps) as a
result of avoiding unnecessary segmentation at the VM tap interface.

When drivers express support for TSO of encapsulated packets, they
only mean that they can do it for one layer of encapsulation.
Supporting additional levels would mean updating, at a minimum,
more IP length fields and they are unaware of this.
No encapsulation device expresses support for handling offloaded
encapsulated packets, so we won't generate these types of frames
in the transmit path. However, GRO doesn't have a check for
multiple levels of encapsulation and will attempt to build them.
UDP tunnel GRO actually does prevent this situation but it only
handles multiple UDP tunnels stacked on top of each other. This
generalizes that solution to prevent any kind of tunnel stacking
that would cause problems.

ipip encapsulated packets can be merged together by GRO but the result
does not have the proper GSO type set or even marked as being
encapsulated at all. Later retransmission of these packets will likely
fail if the device does not support ipip offloads. This is similar to
the issue resolved in IPv6 sit in feec0cb3
("ipv6: gro: support sit protocol").

If the user supply a different fragmentation point or if there is a

SCTP is a protocol that is aligned to a word (4 bytes). Thus using bare
MTU can sometimes return values that are not aligned, like for loopback,
which is 65536 but ipv4_mtu() limits that to 65535. This mis-alignment
will cause the last non-aligned bytes to never be used and can cause
issues with congestion control.
So it's better to just consider a lower MTU and keep congestion control
calcs saner as they are based on PMTU.
Same applies to icmp frag needed messages, which is also fixed by this
patch.
One other effect of this is the inability to send MTU-sized packet
without queueing or fragmentation and without hitting Nagle. As the
check performed at sctp_packet_can_append_data():
if (chunk->skb->len + q->out_qlen >= transport->pathmtu - packet->overhead)
/* Enough data queued to fill a packet */
return SCTP_XMIT_OK;
with the above example of MTU, if there are no other messages queued,
one cannot send a packet that just fits one packet (65532 bytes) and
without causing DATA chunk fragmentation or a delay.

Currently, if a chunk is scheduled to be sent through a transport that
is currently unconfirmed, it will be leaked as it is dequeued from outq
and is not re-queued nor freed.
As I'm not aware of any situation that may lead to this situation, I'm
fixing this by freeing the chunk and also logging a trace so that we can
fix the other bug if it ever happens.

Current code calls irq_domain_alloc_irqs_parent() in .alloc,
so it should call irq_domain_free_irqs_parent() accordingly in .free.
Fix it by switching to use irq_domain_free_irqs_common() instead of
the open-coded private implementation.

====================
flowi6_tos fixes
This set is a follow-up to address Jiri's recent feedback [1] on
the flowi6_tos issue, that it is not used for IPv6 route lookups.
The three patches fix all current users of flowi6_tos and remove
the define to avoid any future confusion on this. Tested the vxlan
and geneve ones with IPv6 routing rules. For details, please see
individual patches.
[ As fixes are currently applied against net-next tree, I've rebased
it against that. ]
Thanks!

flowi6_tos of struct flowi6 is unused in IPv6, therefore dumping tos on
that tracepoint will also give incorrect information wrt traffic class.
If we want to fix it, we need to extract it via ip6_tclass(flp->flowlabel).
While for the same test case I get a count of 0 non-zero tos values before
the change, they now start to show up after the change:
# ./perf record -e fib6:fib6_table_lookup -a sleep 10
# ./perf script | grep -v "tos 0" | wc -l
60
Since there's no user in the kernel tree anymore of flowi6_tos, remove the
define to avoid any future confusion on this.

The struct flowi6's flowi6_tos is not used in IPv6 route lookup, the
traffic class information is handled in the flowi6's flowlabel member
instead. For example, for policy routing, fib6_rule_match() uses
ip6_tclass() that is applied on the flowlabel for matching on tclass,
which would currently not work as expected.

Jiri mentioned that flowi6_tos of struct flowi6 is never used/read
anywhere. In fact, rest of the kernel uses the flowi6's flowlabel,
where the traffic class _and_ the flowlabel (aka flowinfo) is encoded.
For example, for policy routing, fib6_rule_match() uses ip6_tclass()
that is applied on the flowlabel member for matching on tclass. Similar
fix is needed for geneve, where flowi6_tos is set as well. Installing
a v6 blackhole rule that f.e. matches on tos is now working with vxlan.

The recent addition of on-demand i915 audio component binding in the
codec driver seems leading to the unbalanced i915 power refcount,
according to Intel CI tests. Typically, it gets a kernel WARNING
like:
WARNING: CPU: 3 PID: 173 at sound/hda/hdac_i915.c:91 snd_hdac_display_power+0xf1/0x110 [snd_hda_core]()
Call Trace:

[<ffffffffa01192a6>] hda_codec_runtime_suspend+0x76/0xa0 [snd_hda_codec]
.....
The scenario is like below:
- HD-audio driver and i915 driver are probed concurrently at the
(almost) same time; HDA bus tries to bind with i915, but it fails
because i915 initialization is still being processed.
- Later on, HD-audio probes the HDMI codec, where it again tries to
bind with i915. At this time, it succeeds.
- At finishing the probe of HDA, it decreases the refcount as if it
were already bound at the bus probe, since the component is bound
now. This triggers a kernel WARNING due to the unbalance.
As a workaround, in this patch, we just disable the on-demand i915
component binding in the codec driver. This essentially reverts back
to the state of 4.4 kernel.
We know that this is no real solution, but it's a minimalistic simple
change that can be applied to 4.5.x kernel as stable.

nr_cpu_ids can be limited on the command line via nr_cpus=. That can break the
logical package management because it results in a smaller number of packages,

That first branch testing pkg against __max_logical_packages is wrong,
because if the first pkg id is larger, then the find_first_zero will
find us logical package id 0. However, if the second pkg id is indeed
0, we'll again claim it without testing if it was already taken.
Also, it fails to print the mapping.

The peripheral address space is architectural address window which is
uncached and typically used to wire up peripherals.
For ARC700 cores (ARCompact ISA based) this was fixed to 1GB region
0xC000_0000 - 0xFFFF_FFFF.
For ARCv2 based HS38 cores the start address is flexible and can be
0xC, 0xD, 0xE, 0xF 000_000 by programming AUX_NON_VOLATILE_LIMIT reg
(typically done in bootloader)
Further in cas of PAE, the physical address can extend beyond 4GB so
need to confine this check, otherwise all pages beyond 4GB will be
treated as uncached
